The intern finally acknowledged the many dirty looks by fellow passengers, attempts by our driver to close the doors, many warnings that you cannot lean on the doors, and threats that she would kick everyone off the train if whoever was leaning on the doors didn't stop. Said intern acknowledges this by saying "I like how everyone is giving me dirty looks, its not like my foot is sticking outside the doors! You'd think that with all this technology Metro would have a sensor to tell you which car and which door was the problem."
Metro doesn't need sensors to do things like that, they just need you to stop leaning on doors and hitting the door sensors, then trying to pass it off as someone else. Next time try leaning on the wall, or holding on to a railing like the rest of us do.
